  1. Flip mesh motionblur issue

    I always have problems with motion blur for water surface mesh, One time I fixed that problem but I forgot that. as you can see I used a trail SOP to produce velocity for the mesh but the trail SOP creates velocity per point and that's why the motion blur is odd. How can I create proper motion blur for water surface mesh?

  4. I am trying to alter the UVs on a curved wall mesh so that the left and right edges are increasingly stretched horizontally. The attached should make this clear. In the bottom half you can see the green box (which is a rendertexture on the curved wall mesh) is stretched horizontally in the center and appears 'squished' towards the left and right sides. From the viewpoint of the camera it has to appear as a consistent square regardless of where it is poistioned left to right. The top half shows the capture setup with a Ortho Projection camera centered left to right in the curved wall mesh. How can I alter the UVs on this mesh to get my intended result?
  5. Hello, I'm breaking a tree with bunch of branches. So everything work fine with RBD and I manage to create bone for each branch then stick them to the animated rigid mesh. But when I use point deform to deform the original mesh with the bones then I get a heavily distorted result I checked multiple times with attributes and I'm pretty sure the values are matched. I google for weeks and can't get around it. This is the file. I think this amount is enough but if not I can update it right away. I hope someone can point out where did you do wrong. Thank you for reading this. ASk_PointDeform_v2.hipnc

Data exchange between programs without using files. The function may be of interest not only to Houdini users but also to ZBrush users who want to improve their workflow by an order of magnitude 2. Blend Shapes creation in Houdini and ZBrush. Tools optimized for high-poly animated geometry 3. Converting FiberMesh to Houdini Curves 4. Built-in remeshing with ZRemesher. Provides a convenient way for partial remeshing and clean mesh with smart relaxing Product link: https://alexeyvanzhula.gumroad.com/l/nuBwF Lightweight version: https://alexeyvanzhula.gumroad.com/l/RaNuJ
  11. Soft Boolean

    Soft Boolean technology, which was previously part of Modeler for Houdini addon, is now available as a separate product. Soft Boolean tools allow you to stitch polygonal meshes with boolean operations and adding accurate fillets to the resulting geometry. Houdini node can be used with the classical procedural way as well as with the help of special shelf tools. Also, the node can be used in other programs using Houdini Engine. The package contains a plugin for Houdini and some scripts for Maya. Release video: https://vimeo.com/592734907 Product link: https://alexeyvanzhula.gumroad.com/l/iWQyT
  12. Hey Guys, I came across a problem when simulation a vdb-mesh-transition and i was wondering what the proper workflow would be to replace my final mesh (the text in this case) with the text-mesh i was initially beginning with. I've read about point deform but this SOP didnt help me at all.. Im sure there must be a way to replace it in the right way but im just stuck like the total beginner i am.. I would appreciate any kind of help or direction very much!
  13. Flickering Liquid

    Hi there! I have this melting setup with a POP solver, basically scattering some points onto the original mesh and then melting then and meshing back everything again using "particlefluidsurface". So I have been trying to get rid of this flickering on the mesh, I have over 500k points and I also tried increasing the samples and playing with the particle separation in the "particlefluidsurface" I also tried using "vdbfromparticles" but its more or less the same result. I want to know if there is anything I can do to help reduce the flickering? Any help on this is much appreciated Thanks in advance untitled10.mp4
  14. Hello everyone, this is my first post here, I hope everything is I write is clear :::) Im working on a complex wearable, generated from a a simulated sun exposure in houdini. Right now its in a VOP Sop node because it gave an effect close to what im looking for. Like in the photo attached, these gills/petals currently have their opening both facing upwards and downwards, ideally if like to achieve the opening only on the bottom, with a substantial overlap between these gills/petals. The system needs to remain based on the "solar exposure" for the project! If you have and ideas or references about how to achieve this effect please let me know! :::) Wearable_gills_petals.hip Female_naked_smoothed.bgeo
  15. Hello, community! Is it possible to stick UV to deforming topology of an object? I have a growing geometry made with solver and vdb advect. Then I convert vdb to polygons and my UV start floating through geometry. Triplanar also fails to fix it. Number of points is changing constantly and I wonder if there is some technique to make them keep the UV?

  17. UVs and connectivity

    Is there any "real" attribute in a mesh that defines how vertex UVs are connected together? Or is it only implicit, so if two vertex UVs have the same position, they are considered merged? For contrast, in Maya a UV set is considered its own pseudo mesh, with the same UV point connecting to multiple face vertices, its own distinct topology buffers etc.
  18. Convert curve to mesh overlapping mesh

    Hello fellas, I have been trying to create a simple shape using the curve sop and then the intention is to convert to mesh, extrude it and use the ray sop. However, once I convert the curve to mesh, some of the polys on the new mesh overlap each other. I have been trying so many ways to solve this but so far I haven't succeeded. Attached are the images showing what i'm seeing here. Any help is much appreciated. Thanks!
  19. Hi, I am looking for a smart method to fill up bunch of curves/wires inside of tube meshes. Tubes are imported from Maya/blender/3dmax. So far, I am using findshortestPath to fill up wire curves. However, because of using the findshortestPath. it creates bias and curves cannot fill outside bending area. Wires/curve don't need to be super straight from start to end, but no branch. And this tube exists couples, so looking for procedural way as much as possible. If anyone knows smart and better to generate wires procedurally, it would be great. Thanks! findShortestPathInMesh_v004_del.hiplc
  20. Clear VDB Cache after each frame

    Hi, I was wondering if you guys know a good way to clear caches after each frame so the available memory doesnt cause a crash, because its still full from the frame gefore.
  21. Flattening mesh with RaySOP

    Hey Odforce, first time poster here. I am having a difficult time flattening my polygonal mesh to a flat surface using the ray sop. My goal is to have a flat mesh having the same shape my mesh had previous to the ray sop, but everything i can handle to create is this "squeezed" mesh as seen on the screenshot. I tried using the Project geometry node but couldnt get it to work either.
  22. Hello guys. I was wondering how to get the uv's from a rest position (time shift to frame 1) to a deofrming mesh. Otherwise my uvunwrap flicckers and calculates each frame which is not okay. Thanks a lot. P.D: Point number doesnt change.
  23. I saw this video and wanted to replicate the effect for myself for and up coming project, and I wonder if I could get the effect to wrap around a poly surface or mesh.
  24. Hi everyone!!! Started to study houdini. I have separate elements with velocity setup as I want, but couldn't find a way to add any one of them to drive flip fluid. How can I add a velocity of the mesh or curve or the volume to the flip fluid? Or maybe someone can share a tutorial about how it works? In the end trying to create a chocolate swirl or vortex. Thanks.
  25. Hey All! Currently I'm almost a month in now, trying to accomplish something inside houdini as a complete newbie. I was hoping there would be someone out here that has the knowledge to help me out a bit. Every tip is a helpful one for me at this stage entering the amazing world of houdini! So this is what I'm trying to accomplish. I'm trying to simulate a logo inside a big bath full of chocolate that slowly sinks down and drowns in the thick, viscous fluid. I got everything set up with an ocean source, narrow band particle sim and got everything cached. It looks pretty fine, until I continue to the meshing part. I've already spent quite some time trying to get to know the particle meshing tools inside of houdini, and for this case the best one turns out to be the workflow using the VDB toolset (since It gives me the most flicker free results). It get's pretty smooth as well, and I can give it a final smooth using a normals node, followed by a attribute blur that blurs out the point normals. Now comes the part where I'm getting stuck: I'd like to export this to another 3D application. In this case Cinema 4D. But unfortunately, I can't seem to figure out a way to transfer over these smoothed normals to an alembic file. What could I do to render out the pretty result in cinema, like I'm getting in houdini? Thanks a bunch in advance guys! I already learned A LOT from all the crazy talented people on this forum, so thanks a ton for that already. Stay safe,
